Expression and regulation

  • Sigma factor:
  • Regulation: constitutive
  • Regulatory mechanism:
  • Additional information:
    • there is a terminator between rny and ymdB, most transcripts terminate there
    • The mRNA has a long 5' leader region. This may indicate RNA-based regulation PubMed
